Polyhydroxyalkanoates
-3-hydroxybutyrat.svg)
Polyhydroxyalkanoates or PHAs are polyesters produced in nature by numerous microorganisms, including through bacterial fermentation of sugars or lipids.[1] When produced by bacteria they serve as both a source of energy and as a carbon store. More than 150 different monomers can be combined within this family to give materials with extremely different properties.[2] These plastics are biodegradable and are used in the production of bioplastics.[3]
They can be either thermoplastic or elastomeric materials,[citation needed] with melting points ranging from 40 to 180 °C.[citation needed]
The mechanical properties and biocompatibility of PHA can also be changed by blending, modifying the surface or combining PHA with other polymers, enzymes and inorganic materials, making it possible for a wider range of applications.[4]
